Abstract
A controller is provided for HVAC equipment. The controller receives a set of internal temperature values, and a set of external temperature values, the set of external temperature values representing at least one non-current temperature. The controller determines a predictive internal temperature value from the set of internal temperature values and a predictive external temperature value from the set of external temperature values. The controller receives an internal humidity value representing humidity within the premise, the controller further controls the HVAC equipment to modify the humidity within the premise when the received internal humidity value is different from a humidity set point; and the humidity set point is regulated by a humidity limit value, the humidity limit value being where condensation forms, the humidity limit value being calculated using the predictive internal temperature value and the predictive external temperature value.
